The Prophet (peace_be_upon_him) said: Let him who hears of the Dajjal (Antichrist) go far from him for I swear by Allah that a man will come to him thinking he is a believer and follow him because of confused ideas roused in him by him.

Abu Dawood, Book 37, Number 4306:

Narrated Ubadah ibn as-Samit:

The Prophet (peace_be_upon_him) said: I have told you so much about the Dajjal (Antichrist) that I am afraid you may not understand. The Antichrist is short, hen-toed, woolly-haired, one-eyed, an eye-sightless, and neither protruding nor deep-seated. If you are confused about him, know that your Lord is not one-eyed.

‘Uqba b. ‘Amr Abu Mas’ud al-Ansari reported: I went to Hudhaifa b. Yaman and said to him: Narrate what you have heard from Allah’s Messenger (may peace be upon him) pertaining to the Dajjal. He said that the Dajjal would appear and there would be along with him water and fire and what the people would see as water that would be fire and that would burn and what would appear as fire that would be water and any one of you who would see that should plunge in that which he sees as fire for it would be sweet, pure water, and ‘Uqba said: I also heard it, testifying Hudhaifa.

Sahih Bukhari, Volume 9, Book 88, Number 238:

Narrated Al-Mughira bin Shu’ba:

Nobody asked the Prophet as many questions as I asked regarding Ad-Dajjal. The Prophet said to me, “What worries you about him?” I said, “Because the people say that he will have a mountain of bread and a river of water with him (i.e. he will have abundance of food and water)” The Prophet said, “Nay, he is too mean to be allowed such a thing by Allah”‘ (but it is only to test mankind whether they believe in Allah or in Ad-Dajjal.)

Sahih Bukhari, Volume 9, Book 88, Number 239:

Narrated Anas bin Malik:

Narrated Abu Sa’id:

One day Allah’s Apostle narrated to us a long narration about Ad-Dajjal and among the things he narrated to us, was: “Ad-Dajjal will come, and he will be forbidden to enter the mountain passes of Medina. He will encamp in one of the salt areas neighboring Medina and there will appear to him a man who will be the best or one of the best of the people. He will say ‘I testify that you are Ad-Dajjal whose story Allah’s Apostle has told us.’ Ad-Dajjal will say (to his audience), ‘Look, if I kill this man and then give him life, will you have any doubt about my claim?’ They will reply, ‘No,’ Then Ad-Dajjal will kill that man and then will make him alive. The man will say, ‘By Allah, now I recognize you more than ever!’ Ad-Dajjal will then try to kill him (again) but he will not be given the power to do so.”
